The 21-year-old was arrested this morning after the the video went viral on Facebook. Mr. Robinson’s mother, Mary Kirby, told TheDaily News, “He had to be high on something. It’s very out of his character,” she said, defending her son. “He had to be high to do what he did. This isn’t him.” She continued, “He loves animals. He loved his cats, he had dogs, he always loved them.” Mr. Robinson was charged with “aggravated cruelty to animals.”

A veterinarian told The Daily News that the blow could cause serious injuries. According to police, the cat has not been located.

Mr. Robinson has eight previous arrests. In 2011, he was arrested for stealing an iPhone at knifepoint and in another incident, he was caught jumping a turnstile. Six of his eight arrests have been sealed, according to DNAinfo.

Needless to say, Grumpy Cat will be very grumpy when he finds out about this.
